A computer doesn’t send a RST when it gets an unknown packet…
- colanderman 3y agoYes, it does, that is the purpose of RST [1]: > As a general rule, reset (RST) is sent whenever a segment arrives that apparently is not intended for the current connection. A reset must not be sent if it is not clear that this is the case. There are three groups of states: > 1. If the connection does not exist (CLOSED), then a reset is sent in response to any incoming segment except another reset. A SYN segment that does not match an existing connection is rejected by this means. It's possible for a node to be configured not to do this, but this is the default behavior.
